I went into the freezer tonight for something and saw a tub of Cool Whip and I thought "ah, Craig must have bought Cool Whip" and I said it just like Stewie. "Cool Hwip". I don't think I'll ever say Cool Whip normally ever again.
It's like singing jingles when I see certain things. The most annoying is whenever I hear someone mention that they are looking to buy a bike. Inside my head I sing "Buy a Bike! Buy a Bike! Go down to Charnock Richard Cycles. And Buy a Bike!"
I've been doing that for twenty years so I'm looking forward to the day when I'm senile enough to have forgotten the words.
